Máel Dúin mac Áedo Bennán (died 661)[1] was a King of Iarmuman (west Munster) from the Eóganacht Locha Léin branch of the Eoganachta.
He was the son of Áed Bennán mac Crimthainn (died 618), who may have been King of all Munster.
[2] His uncle Áed Dammán (died 634) is called King of Iarmumu in his death obit giving Máel Dúin a possible reign of 633–661.
The roots of this feud are found in an old saga poem Mór Muman and the Violent Death of Cuanu mac Ailchine.
[5] His son Congal mac Máele Dúin (died 690) was also King of Iarmuman.
